Application filed November 20, 1907. ;Seria1 No. 403,014.

To all whom it may concern:

Be it known that l, EuAs GUNNELL, a cit-izen of the. United States, residing at Manito woc, in the county of Manitowoc and State of 5 l' 'isconsin, have invented certain new and useful lmproveme nts in Titntidrii'ting Devices, of which the following; is a specification. l

The invention relates to anti-drifting devices and particularly to such devices as applied to dump scows. Boats of this general type are ilat bottomed and have no rudder. (onserprently dilliculty is encountered in towing them from a tug, as the line used atfords poor control when there is an} wind or current tel'ldiug to swing the scow around. The obje t of the invention is to provide improved means whereby the scow may he effectively controlled by the tug irrespe tive of current and wind, and to this end the invention comprises a drag'means at the rear end of the scow for retarding its movement whereby the line from the tug at the front end of the scow may easily and positively control its movements. Certain embodiments of the invention are illustrated in the v accompanying drawings, wherein F igure, 1 is a side elevation of the scow provided with my invention together with the towing tug attached thereto,

Figure 2 is a plan view of the scow,

Figure 3 is an enlarged longitudinal section through one end of the. scow,

Figure 4 is a transverse section on the line IVIV of Figure 3, V

F igures 5, 6, 7 and 8 are views correspomling to those. of Figures 1, 2, 3 and 4, but having niodiiied'form of a resisting device and operating means therefor, Figure 9 is an enlarged detail section on the line IXIX of Figure 8, and t Figure 10 is a transverse section on the line XX of F igure 2.

Referring to the drawings, 1 thescow which is of the ordinary type and comprises a pair of side portions 2 2" connected together by bulkheads and divisional walls forming a pocket 2 into which the material to be dumped is loaded.

Extending nearly the entire length of the scow and intermediate the side members is the usual well 2, into which the material loaded is finally dumped through the doors 2.

q l l l i l 'l i I l l l l l l l l It is in this well or passage that myantidrifting device is located. This device consists of a pair oi' swinging flaps 3, which flaps are located at both ends of the scow, and are adapted to lie either in the position shown in Figures 3 and 4, at which time they extend across the well, and act as retarding devices, or in positions at right angles to that occupied in Figures 3 and 4, at which time they will lie againstthe sides of the wall and permit the free passage of thewater therethrough. The flaps are operable from the top of the scow h'y means of the-shafts 4, carrying; at their upper ends the levers 5. Stuiiing boxes 6 are provided in the bottom of the scow in order to malie a tight connection between such bottom and the shafts 4Q It will be understood that the flaps at the rear end of the scow are placed in operative. position, when the scow is going ahead, and at this time the flaps at the front end of the ,1 scow are open or in inoperative posit-ion to permit the free passage of water through the well, and when the direction of movement of the scow is reversed, the positions of the flaps at the end are reversed.

The form of construction shown in Figures 5, 6, 7, S and 9 di'tl'ers from that of Figures 1, 2, 3 and 4, in that the retarding tlapsare swung from their upper horizontal edges-instead of their vertical edges, and the means for swinging these laps is di'il'erent from that shown in the other form. Referring partieularly to Figures 7 and 8, it will be noted that the llap 3 is hinged at its upper edge 7 and is swung); by means of the cables 8 attached to the opposite sides of the lower edge oi the [lap and secured at their upper ends to the sprocket chains 9. The sprocket chains S) engage the sprocket wheels 10 mount-ed upon the shaft 1 1 which in turn is carried by the standards 12. The shaft 11 is rotated and locked in position by means of the mech-' anism shown in Figure 9, which mechanism consists of Hu -ratchet wheel 13, the dog 14 having a slight rot-ative movement about the pin 15, the operating lever 16 iivotedto the lug; 17' at its lower end, an carrying above such lower end the pair-of levers 18, which lovers are connected by means of the pin 1!) in position to engage the teeth of the ratchet. On a downward mommntof the, 105 handle 16 the pin 19 engaging-ono of ithe Wind, the flops et desire to secure by teeth of the ratchet, carries it eheed, thus rotst= w the shaft 11. The movement of the v r:

ii fllfl is then reversed the dog 14 holding ratchet from reverse movement until a mop upon the ratchet i3 is secured. It

new will lie seen that when the flops 3 and 3 at the rear end of the seow are in operative poition ext-end ng transversely across the well the movement of such rear end of the sc-ow retarded so that positive control of the is secured by means of the tow end no it result the scow may be prevented from drifting and given any desired neuron i/t hen there is no adverse current both ends are Kept in ntive position. liter mg thus described my invention and illustrated its use, What I claim as no r and Well to retard the lon itudinal movement of the host and in a-not -er position to permit the Water to pass it free; and means for holding the flop in retarding position.

2. The combination wit e scowhevin'g an open bottomed du mping well extenc ing throughout the lenwth of the bottom of the snow, of on anti-drifting flop lying across ihc Well and hinged. along its upper edge, and means whereby the flap may e held in position to ohstruct'the passage of water through the well.

3. combination with a scow hevin on open bottomed. dumping well exten iing throughout the length of the bottom of the soow, of enti-drirting flap lying across the Well and hinged along its upper ed *e, and moons Whei y the flap may he hel either in ohetiueting position across the Well or i l I l i i l l l l j r l eons r folded to permit the free passage oi WSLiZOI through the Well.

4:. The eon'ihinzition with a soon having on openbottomed dumping well extending throughout the length of the bottom of tho soow, of an anti-drifting iiep lying across the Well end hinged along its upper edge, on operating gear on the deck of the scow, 21nd flexible connecting means passing over the gear and connected to the opposite sidesoi the flap for moving such Hop to any desired position.

5. The combination with a. scow having an open bottomed dumping well extending throughout the length of the bottom of tho sco'w, of an anti-drifting ilup lying across the Well and hinged along its up or edge, and op erating means whereby tic flap may he moved to and held in any desired position.

6. The combination with :i scow having an open bottomed dumping well extending throughout the length of the hottom of the scow, of an anti-drifting lop lying :wross the Well and hingml along its up )6! edge, and means operable from thedecic of the scow whereby the lap may he moved to and held in any desired position. v

7. The combination with an anti-drifting flap swinging about a horizortel axis, of 0 erating means therefor comprisinq u flexible connection to the opposite sides oi tho flop, n

sprocket over whici the flexible LODIIGC'LlOIl passes, on operating ratchet for the sprocket, a handle provided with o pivoted o )ernting pat/v1 engaging the-teeth of the sproclret, and a holding pawl for the ratchet.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
